Lewis dot structure in the case of ammonia is depicted by the valence electrons surrounding the nitrogen atom.
The Lewis point structure in the case of NH3 displays that the N atom shares one pair of e- with each of the three H atoms, resulting in a overall of 3 joined pairs of electrons.
The NH3 molecule takes a trigonal pyramidal form because
of the arrangement of the valence electrons according to its Electron
pair Beverage cup structure.
In the Lewis symbol depiction of ammonia, the nitrogen atom is encircled by three points, each representing a pair of shared electrons with a hydrogen atom.
